SAFETY LOCKING DEVICE FOR FHREARMS.

SPECIFIGATIQN forming part of Letters Patent No. 678,420, dated July 16, 1901.

Application filed May 18, 1900.

To all whom it may concern:

Be it known that we, FRANZ NEUBER, a resident of Vienna-Neustadt, and JOSEPH TAM- BO UR and CARL COLBERT,residents of Vienna, in the Empire of Austria-Hungary, subjects of the Emperor of Austria-Hungary, have invented a new and useful Improvement in Safety Locking Devices for Triggers of Firearms, of which the following is a specification.

The object of the present invention is a safety locking device for triggers of firearms, the chief characteristic of which is that the trigger is both prevented from being pulled backward and also insured against lateral movement resulting,as is frequently the case, from impact or shock or the like, while the device is unlocked bysimply gripping the small of the stock in any firing position independently of the placing it against the shoulder. Themeans by which these results are obtained may be various, but consist in principle thereof that a locking and unlocking device lying in a groove in the small of the stock grips the trigger ,by means of a fork or of a projection engaging in a groove in the trigger, and vice versa, or that the said locking and unlocking device holds the trigger for its whole breadth.

In the accompanying drawings, in which similar letters of reference refer throughout to similar parts, Figure 1 is a side view of the safety device locked, the locking and unlocking device. in this case consisting of a lever of the first class. Fig. 2 is a view of the same, but in an unlocked position, being in the position it assumes after the firearm has been discharged. Fig. 2 is a section on the line 2 2 of Fig. 2, looking down, with parts .sisting of a bar which is pressed in a substantially straight line in guides. Fig. 4 is an elevation of the lever seen in Fig. 4. Fig. 4 is a plan thereof. Figs. 5, 6, and 7 represent in section various forms of construction Serial No. 17,111. (No model.)

of that part of the locking and unlocking device which engages the trigger. Figs. 8, 9, and 10 represent in various forms of construction the bow or guard which protects separately the trigger and the locking and unlock-v ing device. The other figures represent details of the various forms of construction of the device.

In the first form of construction the safety device consists of a lever b of the first class capable of turning on the pivot a. The front portion of said lever 12 is normally pressed upward bya spring d in such a manner that the rear portion of the lever, which passes through the trigger-plate of the firearm, projects from the bottom of the small of the stock. The front part of the lever b is forked, as shown in Fig. 2, and within said fork is a step-shaped cross-piece c. In the resting positionthe said cross-piece c is behind a projection f onthe trigger, and the latter is thereby locked in such a manner that the trigger cannot move either backward or sidewise, Fig. 1. When, however, the firearm is gripped by the small of the stock-i. e., in the mannerit is held when being discharged''-the lever b is pressed into the stock, and the cross-piece c is thus moved from the projectionfon the trigger v to a position below the saidprojection. Oonseqnently the trigger is free and the firearm can be discharged. When the pressure on the lever b ceases, the firearm is locked again antomatically-by the upward movement of the front part of the lever by means of spring d, as described. In order that in returning to the locking position no jamming should occur between the trigger and the lever b, the trigger is provided with a pin 9. In the position of the trigger when the firearm has been discharged, the said' pin 9 is above the fork, (see Fig; 2,) and consequently the lever b is prevented from returning to its normalposition until the trigger has been moved forward by the action of the spring jthat is to say, until the trigger has returned to its normal position. by means of a lever of the second class or by means of a bar moving in straight guides, as is shown in the two following forms of construction. In the first thereof the locking device (see Figs. 3 and 3) consists of a lever The same result can be obtained I preferably, of the two similar springs (51.

shown in Fig. 3*, with the exception that the,

cross-piece c in the fork is reversed.- The second of these forms of construction, Figs. 4, 4, and 4 is preferably employed in firearms in which the small of the stock is very narrow andv there is not enough space for the lever 12 to move on its pivot a. In this form of construction no lever is used, but in place thereof a bar I), moving in straight guides.

In this instance the guides consist of two plates '5, fi'xedto the said bar and provided with slots 70, in which the pins Z, fixed to the stock, slide, and vice versa. The spring device'in this form of construction consistIs,

n the two latter forms of construction the lever orbar b is also pressed into a groove in the stock when the smallof the stock is gripped, so that the cross-piece c is moved above the proj ection f and the trigger thus becomes free and the firearm can be discharged.

After the discharge of the firearm the cross piece 0 remains above the projection f' until the trigger has been moved forward by the action of the springj.. Simultaneously with said forward movement of the trigger the lever b is moved back to the locking position by the pressure of the spring (1, so that the device is immediately locked again.

It will be seen that in the forms of construction shown in Figs. 5, 6, and 7 no fork is provided. In these forms the supporting of the triggerby the locking and unlocking device is effected by means of a projection fixed either to the trigger or to the said device and moving in a slot, or the locking and unlocking device lies fiat against the whole breadth of the trigger. In the former form of construction, Fig. 5, the frontpart of the locking and unlocking device is provided with a projection which; runs in a'groove in the trigger. In the second form oficonstruction, Fig. 6, the arrangement of the projection and the groove is rev-ersed,-the said projec- '-tion being fixed to the trigge'r'an'd the groove being in the locking and unlocking device. In the third of these forms of construction the locking andv unlocking device does not hook onto or gripthe trigger, but supports the latter along the whole breadth thereof. In all these forms of construction the advantages possessed by the forked locking and unlocking devices are retained, the trigger being, when the device is locked, protected against backward pull and lateral displacement. In the first two of these forms of construction the locking and the support of the trigger are efiected by means of the projeclocking and unlocking device.

In order to prevent unintentional or accidental operation of the locking and unlocking device, the same is protected by a bow. This bow can be either separate or connected with the trigger-guard. If the trigger and the locking and unlocking device are protected by a common guard, they are divided by a partition in order to prevent pressurein the directionin which the trigger acts, simultaneously operating the locking and unlocking device and causing the unintentional discharge of the firearm.

In Fig. 8 a guard e, surrounding both the trigger and the locking and unlocking device, is'represented, in which a fixed partition separates the two said parts. This is also the case in the form of construction represented ih Figs. 1 to 4. I

Figs. 9 and 10 represent a firearm of' the same kind as shown inFigs: 1 to 4, the trigger of Which'was already provided with the usual guard. A separate guard g has been consequently provided for the locking and unlocking device. This separate bow or guard q can either, as seen in Fig. 9, be in dependent of the trigger-guard p or can be joined to the latter, as seen in Fig. 10.

Having now described our invention, what we claim as new, and desire to protect by Letters Patent, is-

1. The combination of a pivoted lever, a cross-pieceon the forward end thereof, a trigger disposed to be engaged by said cross-piece to prevent both lateral and longitudinal displacement of the same, means movable with the trigger to engage the cross-piece at a predetermined time, and means for retaining said lever in a predetermined position, as set forth. I

2. A new and useful safety locking device for firearm-triggers having a pivoted lever a cross-piece on'the forward end of the same a trigger adapted to be engaged by said crosspiece in a manner for preventing lateral as well aslongitudinal displacement of the same a pin on said trigger adapted to engage said cross piece at a predetermined time and springs for retaining the said lever in a predetermined position substantially as de-' scribed. v

In testimony whereof we have hereunto set our hands in the presence of witnesses.
